FOXBORO FBM219 RH916RH Discrete I/O Module

OVERVIEW

The FBM219 Discrete I/O Module has 24 discrete

input channels and 8 discrete output channels.

Associated termination assemblies (TAs) support

discrete input or output signals at voltages of under

30 V dc, 120 V ac/125 V dc, or 240 V ac.

Depending on the type of I/O signal required, the TAs

contain current limiting devices, fuses, relays, or relay

outputs with internal or external power source and

fusing.

TAs are available which support the functionality of

the 100 Series main FBM07A/B, FBM08. FBM20.

and FBM24A/B/C (16 input main FBMs), when these

main FBMs are used with expansion FBM14.

FBM15. FBM16. FBM27 or FBM42 (8 input/8/output

expansion FBMs).

FEATURES

Key features of the FBM219 are:

 Twenty-Four (24) discrete inputs

 Eight (8) discrete outputs

 Supports discrete input/output signals at

voltages of:

• 15 to 60 V dc

• 120Vac/125 V dc

• 240V ac

 Each input/output is group isolated

 Compact, rugged design suitable for enclosure in

Class G3 (harsh) environments

 Executes the Discrete I/O or Ladder Logic

program, with the following configurable options:

Input Filter Time, Fail Safe Configuration, Fail

Safe Fall-Back, and Sustained or Momentary

Outputs

 Various Termination Assemblies (TAs) that contain

high voltage attenuation and optical isolation for

inputs

COMPACT DESIGN

The module has a compact design, with a rugged

extruded aluminum exterior for physical protection of

the circuits. Enclosures specially designed for

mounting the FBMs provide various levels of

environmental protection, up to harsh environments,

per ISA Standard S71.04.

VISUAL INDICATORS

Light-emitting diodes (LEDs) incorporated into the

front of the module provide visual indication of the

Fieldbus Module operational status, as well as the

discrete states of the individual input and output

points.

EASY REMOVAL/REPLACEMENT

The module can be removed/replaced without

removing field device termination cabling, power, or

communication cabling.

FIELDBUS COMMUNICATION

A Fieldbus Communications Module or a Control

Processor interfaces to the redundant 2 Mbps

module Fieldbus used by the FBMs. The FBM219

accepts communication from either path (A or B) of

the 2 Mbps Fieldbus- should one path fail or be

switched at the system level, the module continues

communication over the active path.

MODULAR BASEPLATE MOUNTING

The module mounts on a DIN rail mounted baseplate,

which accommodates up to four or up to eight

Fieldbus Modules. The Modular Baseplate is either

DIN rail mounted or rack mounted, and includes

signal connectors for redundant Module Fieldbus,

redundant independent dc power, and termination

cables.

SECURITY

Field power for contacts or solid state switches is

current limited.

TERMINATION ASSEMBLIES

Field I/O signals connect to the FBM subsystem via

DIN rail mounted TAs. The TAs used with the

FBM219 are described in See “TERMINATION

ASSEMBLIES AND CABLES” on page 7.
